<div class="description"><div class="ng-directive-page ng-directive-nginit-page"><p>The <code>ngInit</code> directive allows you to evaluate an expression in the
current scope.</p>
<div class="alert alert-error">
The only appropriate use of <code>ngInit</code> is for aliasing special properties of
<a href="api/ng.directive:ngRepeat"><code><code>ngRepeat</code></code></a>, as seen in the demo below. Besides this case, you
should use <a href="guide/controller">controllers</a> rather than <code>ngInit</code>
to initialize values on a scope.
